Tyler, you should really consider becoming an official contributor to this site -- your advice is always excellent.
Desiree, in addition to following Tyler's advice, you might want to start by doing some research and making a list of what social restrictions and conventions existed at the time the author was writing. After all, until you know that, how can you know which ones Elizabeth ignores? Then, list the ways in which she violates those conventions. That should give you enough for a freewrite or first draft, which you can then post here for more feedback.
